ORGAN PIPE.

Application filed July 15, 1921. Serial NO. 484,861.

To all whom it may concern:

Be it known that 1, CHARLES BARK- STROM, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Organ Pipes, of which the following is a specification.

This invention has general relation to improvements in pipe organs, and particular relation to the pipes thereof, and it consists in certain peculiarities of the construction, novel arrangement and combination of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide an organ pipe of such construction and arrangement of its parts, that the pipe as a whole may be readily and properly mounted on and in communication with tl e wind-chest of an organ, and in such a man- 7 ner that when so mounted its parts can be easily adjusted for tones or for cleaning or repairing the device. I

" In the accompanying changing or regulating parts of drawing which serves to illustrate an embodiment of the invention- Fig. 1 is a central vertical sectional view of the pipe taken on line 1-1 of Fig. 2 lookin in the direction indicated by the arrows.

Fig. 2 is a front view in elevation showing the pipe shortened for convenience of illustration.

Fig. 3 isan enlarged cross-sectional plan view taken on line 3-3 of Fig. 1 looking in the direction indicated by the arrows.

Fi 4 is a similar view taken on line 4- 1 of Fig. 1 as indicated by the arrows.

Fig. 5 is a detached perspectlve view of a modified form of the coupling sleeve employed for uniting the lower end of the pipe to the foot thereof,

Fig. 6 is a detached perspective view of the locking device for said coupling, and

Fig. 7 isa side view of the key to be used for adjusting the movable cap of the device.

Corresponding numerals of reference refer to similar parts throughout the dilierent views of the drawing.

, The reference numeral 10 designates a portion of the wind-chest of an organ within a suitable opening 11 in the upper portion of which is located the lower end of the foot 12 of the pipe. This foot may be, made of any suitable material but by preference of wood. As shown, thefoot 12 is downwardly tapered at its lower portion, but is annularly enlarged as at 13 above its longitudinal middle. At the upper end 'of the enlarged portion 13 the foot 12 is provided with a reduced and upwardly extended portion 14, which portion has at its upper end an inwardly extended flange or closure 15 for the upper portion of the chamber or cavity 16 in the foot 12, which cavity, it will be observed, is of greater diameter than the bore or channel 17 with which the foot is longitudinally provided. By providing the foot with the reduced portion or extension 1 1, it is obvious that an external shoulder 18 will be provided, against which the. lower end of the pipe 19 will rest when said pipe is fitted on the foot.

By reference to Figs. 1 and 4 of the drawing, it will be seen and understood that the inwardly Xtended flange or closure at the upper end of the reduced portion 14 is segmental in shape and is provided with an upwardly and outwardly beveled straight edge 20 which cooperates with the slidable cap 21 as well as the upper cap 22 of the pipe for producing sounds. At the straight edge of the flange or closure 15 the reduced extension 14 is cut away longitudinally, thus providing spaced walls 23, on which the slidable cap 21 may rest for the purpose of partially closing the cavity or chamber 16 of the reduced portion 1 1 of the foot 12 of the device. The cap 21 has a plane inner surface to rest on a similar surface 21 provided on the enlarged portion 13 of the foot 12 and extended longitudinally therewith. The outer surface of the cap 21 is arcuate in form to fit snugly yet movably between the coupling sleeve and foot of the device as will be presently explained.

The coupling sleeve is designated as a whole by the numeral 24, and may be made of any suitable size and material, but preferably of sheet metal bent to form substantially a split tube of sufficient size to fit snugly around the lower portion of the pipe 19 and that portion of the foot 12 directly below the lower end of said pipe. This sleeve has at its upper end laterally extended and spaced ears or flanges 25, which, when the sleeve is in its operative position on. the device, will stride the elongated open ing in the lower end of the pipe 19 which coincides with the cut away portion of the re duced part 14 of the foot. The adjacent edges of the sleeve 21 below the ears 25 Q greases thereof are each provided with interlocking tongues 26 which are bent outwardly and then inwardly to form hooks or engaging guides for a key 27 wnich is slightly tapered towards its lower end and has said end rounded as is clearly shown in 2 to en able it to be easily inserted between the engaging hooks 26 ot' the sleeve. This key is provided at its upper end with an shaped extension which serves the double function of forming a catch by means of which the key can be inserted and removed from between the hooks 26, and what is known in the art as a heard 99. The heard 29 on the key 27 is enrployed in connection with a string tone pipe, but may be omitted when used in connection with a fine tone pipe.

As the surface of the enlarged portion of the foot below and in alignment with the slot or cut-away part ot' the reduced portion 14 thereof is flattened, and as the tubule port-ion oi the coupling sleeve 24-. surrounds the foot at said flattened portion. it is evident that the slidable cap ill. can. be inserted between said sleeve and foot by placing the upper end of said cap between said parts and forcing it upwardlv until its upper end approaches the straight edge of the iiange or closure 15 as will be readily understood by reference to Figs. 1 and 2 of the drawing. hen thus positioned, the key 2? can be in sertcd between the catches 26 which operation will cause the adjacent edges oi the sleeve to be drawn towards each other and thus tightly hold the coupling sleeve in position on the lower end of the pipe 19 and the upper portion of the foot 12 of the device.

To tin-couple or disconnect the parts, it is manifest that the key 27 may be removed upward pressure thereon, thus freeing the same from the hooks 26 and thereby allowing the sleeve to expand to a sutlicient e:;- tent to permit it being slid up or down, or if desired, the above operation can be employed when it is necessary or desirable to adjust the beard on said key with respect to the lips of the pipe.

In Fig. 5 I have shown a modification in the construction ot the coupling sleeve. which consists 01 a piece of sheet metal bent to form a split tubular member 30 which is provided as in the other construction with spaced parallel cars in its upper portion to stride the elongated slots or openings in the lower end of the pipe and in the upper end of the reduced portion l t oi": the toot. In this modification. that portion of the sleeve 30 below the ears thereon has its adjacent edges each provided with an out wardly turned hook 31 which hooks converge upwardly as is clearly shown in i 5 of the drawing.

To clamp and lock the sleeve of the inedilied form in place on the pipe 19 and foot 12,

I employ a key of sheet metal which is provided at each of its edges with an inturncd flange to engage the outwardly turned hooks 31 oi the sleeve 30. The flanges S15 oi the key converge upwardly to the e id that, by placing the lower Dart oi the key 32 over the upper ends of the hooks 3'1, and then sliding the key downwardly thereon, said hooks will be iorced towards each other and thus t' 'htly clamp the sleeve on the pipe and body.

is clearly shown in Fig. l, the lower end of the toot has titted therein a tubular toe Jll, which too is made of soft metal and is provided in, its tapered lower end with an oriiice 35 which can be enlarged if desired, l able instriunent oy the insertion ol .1 sui therein for gouging out or cutting away said opening to the end that a greater volnine of air may be permitted to pass into the pipe from the wind-chest.

The toe 254: '5; located in a vertical opening 36 in a. partition oi, the wind-chest directly below the opening ill in which the foot is liiicated. The lower end of the toe Set is positioned about [lush with the lower surface oi said partition and is closed by means oi a valve 37 connected to a pneumatic 38 which may be operated by akey (not shown) oi the organ united to said pneumatic by means of suitable connections 35) leading through the floor of the wind-chest.

lin order to readily adjust the slidable cap 2i, provide the foot 12 on its front face a a suitable (,llSttllltB below the coupling lecve with an opening 4:0 for the reception the heel il on the blade d2 of the key shown in T of the drawing. The blade oi this key is adapted to fit in an open \inea, ib a; in blade t a niay slot l3 near t lower end of the cap 21, z. iii'est that by turning the in the proper direction. the said be suitably adjusted.

i thus iully lescribed my invention, 1 ciann as new and desire to secure by atcnt is:
